Dynamic Date Dropdown Select Menu in PHP

Use PHP to create dynamic drop down menu for date selection

Here is a snippet of PHP code to create a dynamic form field containing day, month and year selection fields.

The PHP code below consists of a simple function which you can echo from within your form to give it date fields dynamically. The year can go all the way up to the current year, or can be limited by an age requirement.

The PHP date select function:

01	function date_dropdown($year_limit = 0){

02	$html_output = '    <div id="date_select" >'."\n";

03	$html_output .= '        <label for="date_day">Date of birth:</label>'."\n";

04

05

/*days*/

06	$html_output .= '           <select name="date_day" id="day_select">'."\n";

07	for ($day = 1; $day <= 31; $day++) {

08	$html_output .= '               <option>' . $day . '</option>'."\n";

09

}

10	$html_output .= '           </select>'."\n";

11

12	/*months*/

13	$html_output .= '           <select name="date_month" id="month_select" >'."\n";

14	$months = array("", "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");

15	for ($month = 1; $month <= 12; $month++) {

16	$html_output .= '               <option value="' . $month . '">' . $months[$month] . '</option>'."\n";

17

}

18	$html_output .= '           </select>'."\n";

19

20

/*years*/

21	$html_output .= '           <select name="date_year" id="year_select">'."\n";

22	for ($year = 1900; $year <= (date("Y") - $year_limit); $year++) {

23	$html_output .= '               <option>' . $year . '</option>'."\n";

24

}

25	$html_output .= '           </select>'."\n";

26

27	$html_output .= '   </div>'."\n";

28	return $html_output;

29

}

It’s usage:

view sourceprint?

01	<form action="" method="post">

02

03	<label for="name">Name:</label>

04	<input type="text" name="name" />

05

<?php

06	echo date_dropdown();

07	//or limit by age requirement

08	echo date_dropdown(18);

09

?>

10	<input type="submit" name="submit" value="submit"/>

11

</form>
